Just finished reading the latest issue of Diesel Power magazine. Some pretty interesting stuff. Of special interest was the short article starting on page 118 on the 1289hp Flagship. Does anyone believe that truck made that much HP on #2 only with that setup? Must be a typo on the #2 only. Or it's the friendliest dyno on earth. I seriously doubt that set of twins is capable of that much HP on #2 only. Probably can with all that NOS in the bed. They certainly won't win any beauty contests either.
